Gambling Harms Severity Index Calculator

Calculate your transformed GHSI-SF score.

Converter Tool

The converter tool lets you convert any score on one of our benchmarked scales to a Rasch Measure. The Rasch Measure lets you read compare to other scales that we also have benchmarked as well as comparing gambling-related hamrs to decrements to wellbeing.

For more details on the Rasch conversion process click here.

Available Instruments:

• PGSI (Problem Gambling Severity Index): A 9-item screening tool that assesses gambling behavior and related harm
• DGHS7 (Gambling Harms Scale): A 7-item scale assessing a range of negative consequences of gambling

Enter your raw GHSI score to see your transformed score and interpretation.

About the Gambling Harm Measures

This calculator provides conversions for multiple gambling harm measurement instruments, transforming raw scores into interval-level Rasch measures (logits).

Key Interpretations:

• Minimal (< -6.0 logits): Few or no gambling-related harms
• Low (-6.0 to -3.5 logits): Minor harms with limited impact on wellbeing
• Moderate (-3.5 to -2.3 logits): Noticeable harms affecting some areas of life
• Moderately Severe (-2.3 to 0.5 logits): Significant harms with substantial impact
• Severe (> 0.5 logits): Extensive harms with major consequences across multiple domains

Rasch Details

The Rasch transformation produces an interval-level measure that more accurately represents the severity of gambling-related harm compared to raw scores.
